WINDSHIELD ARTIcuLArEnpEvIcE WITH MECHANICAL nocKIne Means.

To all whom it may concern:

Be it known that LADIS LEWKOWIOZ, citizen of the United States, residing at Paris, France, has invented certain new and useful Improvements in Windshield Articulated Devices with Mechanical Locking Means, of which the following is a specification. V

The object of this invention is to eifect improvement in the construction of the pivotal joints of wind shields to enable the shields to be arranged at will either in vertical or inclined position, and to be secured in either of such positions, a further object being to provide devices of this kind which are simple in construction, which may be readily operated, which are not likely to get out of order, and which can be manufactured at minimum cost. I

With the above and other objects in view, the invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

The object of the present invention is therefore to reduce the cost price, and to enable to manufacture in large quantities simple and strong wind-shields.

In the annexed drawing, is shown by way of example-explicatiw but not limitative a realization of the invention, in which:

Fig. -1 is a front elevation of a portion a wind shield embodying my improvements.

Fig. 2 is a vertical sectional view ofthe same.

Fig. 3 is aside elevation of the same;

Fig. 4 is a vertical sectional view of the same, on a plane at right angles to that of Fig. 2. Y Y

My improved wind shield construction includes a member 1 which is aflixed to the member 2 which forms the frameof the section 3 of the wind shield. Said member 1 is provided with a recess 4 which has a vertical rear wall 5 and an inclined front wall 6 which converges upwardly toward'the rear wall. A recess 4 communicates with a recess 7 in which is located the spring of the locking device. The wind shield 8 is provided at its sides with pivots 10 which are fixed on the members 1.

The sides 9 are provided with arms.

of recess 7. Said spring holds the loc king device 11 in position,'and is helped lby the little spur 15 which locates itself in the 1 provided in part 2 fixed to i little recess 16 the section It is easy to understand'from the drawings that, whenever it is wished to put thev wind-shield in the inclined position when same is in the verticle position, it is 'sufiicient to pull the button12 so that locking-device 11 be brought into recess 4, leaving between said recess and the remaining mechanical part enough space to allow arm 9 to move' towards the wind-shield side; When arm.

9 butts against wall 6, 'it' is suflicient in of the button 12. The locking device '11 locates itself then against the opposite face of arm 9 and will hold rigidly said' arm against wall 6. g

It is understood that the present invention is not strictly limited to the example above-shown and represented, but that it can assume various forms, proportions, dnnensions and be for or of various materials as need be.

order to hold it in this position to'let go Having now described and'ascertained the nature of my invention, what I claim is:

1. In a wind shield, a supporting mem' ber having a recess provided with a vertical inclined front wall, a member pivotally mounted on said supporting member and having an arm extending intosaid recess between the said walls thereof, and means, ar-

ranged in said recess, to bear against said same against either of said arm and lock the walls. 1

2. In a wind shield, a supporting member having a recess provided with a vertical rear wall and a rearwardly rear wall and a rearwardly and upwardly and upwardly inclined front wall, a member pivotally mounted on said supporting member and having an arm extending into said recess between the said Walls thereof and means, arranged in said recess, to bear against said arm and lock the same against either of said walls, said locking means comprising a substantially triangular member, a stem
